The correct answer to this requires more information. The answer to your question as posed:
1. 100 Mb x 4 = 400 Mb/sec or 50MB/sec There are 8 bits per byte 400M/8 =50M
2 There are 20 x 50MB in one GB, 1000 GB in one TB.
3. 1000 x 20 = 20000 seconds or about ~5.5 hours.
The reason this is not all that useful:
1. transmission protocols over slower lines can use compression, example ssh2 using compression: Depending on the data you might get 70% compression. Or 10%.
2. There is overhead for protocol packets, ex: MTU size affects the percentage of data per packet assuming TCP/IP, larger packets are more efficient. Not all hardware can deal with large packets.
3. controllers generally will not let you completely saturate a given line, as kind of a bandwidth limit. Especially if:
4. other processes compete for the same line transmission resource.
5 if you eat the transmission line for 5.5 solid hours the political feedback may not
help your career path where you are. You may want to use just 3 of the 4 transmission lines, so other work can continue.
Your best answer is to time the transmission with a smaller data chunk (example 5% of the size) and multiply that result times 20.
